CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority of U.S. Provisional Patent Application 61/509,942 filed Jul. 20, 2011, the contents of which are incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates to systems and methods for providing post-operative treatment and, more particularly, to such systems and methods for providing continued treatment alter cataract surgery.

BACKGROUND OF THE INVENTION

After cataract and other eye surgeries, antibiotics need to be administered every few hours for several days. In addition, other medications such as anti-inflammatory drugs also need to be administered frequently. The drugs are typically delivered to the ocular surface and the front of the eye in the form of eye drops. Currently, almost all cataract surgery is performed as outpatient or ambulatory surgery leaving the follow-up administration of anti-infective and anti-inflammatory medications to the patient or other in-home care giver.

While the patient invariably receives at least one prescription to fill for their drugs, they oftentimes require additional post-operative aids or devices to improve their recovery. For example, doctors will frequently provide sunglasses to combat light sensitivity and an eye shield to wear while sleeping. The various elements of post-operative cataract care are therefore known, but they have never been offered together in a comprehensive convenience kit.

Particularly, doctors usually do not fill prescription medication orders in-house. The prescriptions are filled through a pharmacy. The doctor is often relied upon to provide the protective hardware e.g., sunglasses and shields), but a doctor's office or surgical center has a. primary purpose of treating the patient and not necessarily supplying their patients with post-operative aids. A pharmacy, while likely to have a selection of sunglasses and other post-operative aids, is primarily a drug dispensary and the needed post-surgery aids may not be provided.

Lastly, a typical post cataract surgery course of treatment includes three prescription medications. Sometimes one or more of these three individually prescribed medications is not available at the pharmacy, requiring the patient to fill that prescription at another pharmacy or to call the doctor to alter their prescription to an equivalent/available medicine.

Post-operatively, patients of cataract surgery have impaired vision for a day or so and are encouraged not to drive for at least that time. Unless they have a caregiver that can. collect the prescribed pharmaceuticals and the needed post-surgery aids, they may not receive the benefits of these products on a timely basis.

There is therefore a need for a convenient and reliable system and method to provide both the prescribed medications and all of the needed post-operative aids to a patient.

SUMMARY OF THE INVENTION

In accordance with one form, of this invention there is provided an improved convenience kit having both prescribed eye medications and protective devices to improve a patient's overall treatment after cataract surgery. The present invention offers convenient combination therapy for improving overall post ocular surgery treatment and also providing protective hardware to reduce the likelihood of irritation or discomfort while the patient heals. The kit of the invention comprises a topical antibiotic, a topical non-steroidal anti-inflammatory medication, a topical steroidal anti-inflammatory medication, an eyewear apparatus, and an eye shield. In one non-limiting embodiment, the kit of the invention comprises only the topical non-steroidal anti-inflammatory medication along with an eyewear apparatus and an eye shield.

The various embodiments of the present invention facilitate the prophylactic administration of at least a non-steroidal anti-inflammatory medication while also providing the patient with approved protective devices in a single convenient it that can be prescribed under a single National Drug Code.

DETAILED DESCRIPTION OF THE INVENTION

Controlling the most common post-surgery complications related to cataract and other eye surgeries typically involves prophylactic administration of medications along with protecting the eye from further irritation. An example of such a complication is bacterial conjunctivitis. Ameliorating the inflammatory conditions related to these complications is typically achieved with several eye drops containing anti-infective and anti-inflammatory drugs.

Positive therapeutic effects have been achieved with patient/self-administered formulations of standard antibiotics, corticosteroids, and non-steroidal anti-inflammatory drugs following cataract surgery to prevent and treat post-operative inflammation and infection.

After surgery several problems associated with the eye, including inflammation and irritation, can be traced to bacterial infections (e.g., conjunctivitis). It is imperative for proper healing and future ocular health that the eyes are treated against post-surgery infections, It is also important to ensure that the patient physically protects their eyes during the healing process. The post-surgery cataract treatment kit 10 of the invention is adapted to provide for both the medicative therapy and physically shielding the eye from potential damage.

For convenience and before further description of the present invention, certain terms employed in the specification are collected here. These definitions should be read in light of the remainder of the disclosure and understood as by a person of skill in the art.

The phrase “effective amount” is an art-recognized term and refers to an amount of an agent that, when incorporated into a pharmaceutical composition of the present invention, produces some desired effect at a reasonable benefit/risk ratio applicable to any medical treatment. In certain embodiments, the term refers to that amount necessary or sufficient to eliminate, reduce or maintain (e.g., prevent the spread of) a symptom of ocular infection, or prevent or treat an ocular infection, such as conjunctivitis. The effective amount may vary depending on such factors as the disease or condition being treated, the particular composition being administered, or the severity of the disease or condition. One skilled in the art may empirically determine the effective amount of a particular agent without necessitating undue experimentation.

The term “treating” is an art-recognized term which refers to curing as well as ameliorating at least one symptom of any condition or disease.

The term “preventing,” when used in relation to a condition, such as conjunctivitis, is art recognized and refers to administration of a composition which reduces the frequency of, or delays the onset of, symptoms of a medical condition in a patient relative to an individual that does not receive the composition.

FIG. 1 refers to one embodiment of the post-surgery cataract treatment kit 10 of the invention. The kit 10 comprises a first container 12 comprising an effective amount of antibiotic medicine: a second container 14 comprising an effective amount of a non-steroidal anti-inflammatory (NSAID)medicine; and a third container 16 comprising an effective amount of a corticosteroid anti-inflammatory medicine. In the preferred embodiment, each container 12-16 is an eye dropper containing a topical liquid solution of the respective medicine. The kit 10 further comprises sunglasses 20 and an eye shield 22 with a nonirritating adhesive tape 22.
